2. Search your system for winsock.scr, and delete the file if you find it. Make sure your system is set to show hidden files and folrders:

Open Windows Explorer, and in the Folder Options->View settings under the Tools menu, select "show hidden files and folders", and uncheck "Hide protected operating system files" and "Hide extentions for known file types".

3. Run HijackThis again. If winsock.scr has reappeared in the "F2" log entry, you can try to manually remove the reference from the Registry:

Go to Start, Run, and type in regedit; click OK and the registry editor will open.

Before you edit the registry, you should make a backup. At the top of the Registry window, click on the Registry menu, click Export Registry File. In the Export range panel, click All, then save your registry as Backup
